Advanced internal parting surface technology is usually adopted in the design of Auto bumper mould. The advantage is that the parting line is hidden on the non-appearance surface of the bumper, and the parting line cannot be seen after being assembled on the car, which will not affect the appearance of the product. However, the difficulty and structure of this technology are more complicated than that of the outer parting type bumper, and the technical risk is also higher. The cost and price of the Auto bumper mould will also be much higher than that of the outer parting type bumper. It is widely used in high-end cars.
